When can Early Extension occur within the golf swing?

Early extension can occur throughout various phases of the swing due to how the body moves in relation to the club and the ground. This phenomenon typically arises as the hips and pelvis shift towards the golf ball too early in the downswing, which can stem from improper sequencing or body mechanics. However, early extension is not confined to just one moment like the top of the backswing, the downswing, or at impact.

It may manifest during the transition from the backswing to the downswing as well as during the follow-through, depending on the golfer's posture and their ability to maintain the proper angles throughout the swing. The body’s movements can vary significantly among different golfers, meaning that early extension is a complex issue that isn't limited to a single phase of the swing. Understanding that it can occur at multiple points offers a clearer picture of how to analyze and improve swing mechanics holistically.
